Nutritionist George Lockhart will be making some tweaks for Conor McGregor, in preparation for Floyd Mayweather.

On August 26th, Conor McGregor will be taking on his first professional boxing match against Floyd Mayweather. And in preparation for it, his team his rightfully changing up some of their training rituals, except for wrestling and jiu-jitsu which apparently is still part of McGregor’s gym routine.

For one, nutritionist George Lockhart has been tweaking McGregor’s diet. Speaking to MMA Junkie, Lockhart revealed what the team has been working on in terms of weight management, and how it translates to the fight.

“With an MMA match, wrestling, (jiu-jitsu and) having someone on top of you, weight matters – with wrestling it does have a huge effect. With boxing, I believe speed is key,” Lockhart said. “If I’m bigger than you but can’t hit you, it doesn’t make a whole lot of difference. Not as much grappling, the referee pulls you apart as soon as that does happen.”

“I want to make sure the fighter is lower in weight, the cut is not as big and the reload is not as much.”

Lockhart, who has also worked with other top fighters, has seriously taken the different rule set into consideration, and how the weight management this time around could work towards their advantage.

“For an MMA fighter to reload, they’ll gain 15, 18 pounds, which gives them that advantage (on fight night). Boxing, I want him actually walking in close to weight the week of the fight. Walking in, weighing in and maybe gaining a couple pounds after that.”

Mayweather vs. McGregor is slated at 154 pounds and will be held at the T-Mobile Arena in Las Vegas.
